i kno we have all come across this guy "oh i kno what you did on that one" or "that wasent that great i could do that" you know that kind of guy. what do you do in these situations obviously you wouldent show any tricks to him but what if your in a group of people and everyone is demanding to see a trick you can but dont want to refuse but theres just that one guy who feels thretend i guess, so he feels like he has to state that he knows how the tricks are done or that they arent that impressive so he can be the "smart guy" or somthing i know you guys know who im talking about. any thoughts?
